Joshua invested $750 in an account paying an interest rate of

Maslowich

Due to the difference in the interest rate and the quarterly compounding, Joshua will have $212.24 more than Josiah.
Step-by-step explanation:
Giving the following information:
Joshua:
Initial investment (PV)= $750
Interest rate (i)= 0.0341/4= 0.008525
Number of periods (n)= 18*4= 72 quarters
Josiah:
Initial investment (PV)= $750
Interest rate (i)= 0.0285
Number of periods (n)= 18 years
To calculate the future value of each one, we need to use the following formula:
FV= PV*(1 + i)^n
Joshua:
FV= 750*(1.008525^72)
FV= $1,381.98
Josiah:
FV= 750*(1.0285^18)
FV= $1,169.74
Due to the difference in the interest rate and the quarterly compounding, Joshua will have $212.24 more than Josiah.

The tables below show running hours of three printers that produce greeting cards and the total number of greeting cards produce

AysviL [449]

<u>ANSWER</u>

The correct answer is A

<u>EXPLANATION</u>

To find the ink cost of each card coming from printer B, we need to find the total cost from printer B and the total number of cards printed by Printer B.

The total hours of all the three printers over the three weeks

$=40+45+55+50+50+30+45+40+60=415$

The total hours of printer B only

$=50+50+30=130$

Total number of cards produced over the three weeks

$=7950+7800+9600=25350$

We can use ratio and proportion to determine the total cards produce by printer B only.

$415:25350$

$130:x$

If less, more divides

$x=\frac{130\times 25350}{415} \approx7941$

Total cost of Printer B in 130 hours

$ $=130 \times 15=1950$

The ink cost

$=\frac{1950}{7941}$

$=0.2456$

$ $\approx 0.30$

to 2 decimal places

Right triangle ABC is similar to right triangle DEF. If the side lengths for triangle ABC are 15, 20, 25, respectively, which va

solniwko [45]

Answer:

$A = 15$ $B = 20$ $C = 25$

$D = 30$ $E = 40$ $F = 50$

$D = 3$ $E = 4$ $F = 5$

Step-by-step explanation:

Given

Similar Triangles: ABC and DEF

$A = 15$

$B = 20$

$C = 25$

Required

Determine the sides of DEF

No options were given, so I will solve on a general terms.

Since both triangles are similar, then the following relationship exists.

DEF = ABC * n

i.e.

$D = A * n$ $E = B * n$ $F = C * n$

Where

$n = Scale\ Factor$

Assume n = 2.

So, we have:

$D = A * n$

$D =15 *2$

$D = 30$

$E = B * n$

$E = 20 * 2$

$E = 40$

$F = C * n$

$F = 25 * 2$

$F = 50$

Assume $n = \frac{1}{5}.$

So, we have:

$D = A * n$

$D =15 *\frac{1}{5}$

$D = 3$

$E = B * n$

$E = 20 * \frac{1}{5}$

$E = 4$

$F = C * n$

$F = 25 * \frac{1}{5}$

$F = 5$

So, the possible sides are:

$A = 15$ $B = 20$ $C = 25$

$D = 30$ $E = 40$ $F = 50$

$D = 3$ $E = 4$ $F = 5$

Which shapes can the composite figure be divided into to find the area

icang [17]

Given:

Composite figure

To find:

The shapes in the composite figure.

Solution:

The image splitted into three shapes.

Draw a line from top vertex to bottom vertex.
We get one triangle.
Similarly, draw another line adjacent to the previous line.
We get another triangle and rectangle.

Therefore a composite figure divided into a rectangle and two triangles.
